Searches of this phrase and iterations returned no Japanese results, sorry. I tried to look up the words in Chinese dictionaries, but as I don't know what I'm doing, I had little success.

The 4th character from the bottom is 后. Probably. Maybe. (I have no idea??!?!) It is the only character I could find that remotely resembles the one on her back. If the tattoo were Japanese, it could be た but... how do you manage to write た like that ?! There is like an extra stroke and the vertical line does not look like a full stroke through the horizontal line. Well, 后 also has a long vertical stroke. And the square isn't closed properly. But since combinations of the other 3 characters did not return any Japanese words, this is the conclusion I have drawn.

Good luck (n_n).V,,

It would help your case if you could find the source of the image, the person's name, a video, photo collection, Facebook account, etc. If it's on something like Facebook, you could ask them to tell you, or take a clearer photo if they don't know either. If it were a celebrity, you could look up "what does this pop star's tattoo say?" and you'd probably be able to find the answer quickly.

The first character is 愛 and the second looks to me like 危, other than that I think they are as Pianogirl-san says. If it is Japanese I cannot understand it. It could represent English letters or have something to do with the person as the OP said, but it is also possible that she chose those characters for their meaning.

You should check out Hanzismatter for why it probably doesn't mean anything, even if the tattooed girl meant for it to. Japanese and Chinese don't get kanji/hanzi tattoos, and Westerners that do end up with stuff that's missing strokes, doesn't mean what they wanted, and in general the results are laughable for anyone who understands either language.

I've never had the notion that it could even plausibly be a good idea at any age. I don't think I could even be with a girl that would get one because we'd clearly just never understand each other on some fundamental level.

Hashimoto launched the crusade to eradicate tattoos from the public sector, saying that the local government would block the promotion and advancement of any city employee who declined to respond to the survey asking them if they have tattoos.

right-wing and bat shit crazy. I don't like tattoos either but that's just a tad ridiculous
